Edge On A Trigger (Enhanced)
While state condition A is met, the DL850E/DL850EV triggers on the OR of multiple trigger source edges.
Edge detection
Trigger Condition A is being met
Trigger Source
You can use CH1 to CH16 and Bit 1 to Bit 8 as the trigger sources. Bit 1 to Bit 8 appear as options when a logic
input module is installed in a slot.
State Condition (A State)
To set state condition A, select the states of the trigger sources in relation to the trigger level.

State Condition Achievement Condition (Condition)
Select whether the result of comparing the trigger source states to their specified conditions must be true or false
for the state condition to be considered met.
True The result must be true.
False The result must be false.
Edge Detection Condition (Edge)
Set the condition for detecting the trigger source edge.
An edge is detected when the trigger source changes from a level
below the trigger level to a level above the trigger level (rising).
An edge is detected when the trigger source changes from a level
above the trigger level to a level below the trigger level (falling).
− The signal is not used as a trigger condition.
Trigger Level (Level) and Trigger Hysteresis (Hys)
Set these items for each trigger source.
These items are the same as the trigger level
and hysteresis of the simple trigger.
Trigger Hold-Off (Hold Off), Trigger Position (Position), Trigger Delay (Delay)
These items are the same as trigger hold-off , trigger position , and trigger delay
of the simple trigger.
